bug#2222: 23.0.90; Labels in RMAIL

Labels in Rmail no longer provide completion as they did.  I realise
this is because the Babyl format maintained a list of labels at start
of the file, but this is a loss of functionality.  Surely which
scanning for the ^From lines one could maintain a label list?
  Would also help towards stopping multiple identical labels
  perhaps...
